I would start 1st Playthrough on Normal Mode, 2nd Playthrough on Valhallan Mode then Clean up on easy mode because Valhallan mode can be difficult sometimes and Normal Mode will let you know what to expect on Valhallan Mode. You can do Easy mode then Valhallan Mode if you choose.

There are a lot of Missable Trophies! You can do them in your 1st or 2nd Playthrough, I would try and get most in the 1st Playthrough so that there won't be much to do in the 2nd Playthrough.

When going for a Missable Trophy if you fail just quit the game and load up the continue and you will be back at the last autosave. You will be doing this a lot and it saves you from doing another Playthrough.

The General & Combat Feats are easy to do and you can look them up on the Menu by pressing and looking at them under Moves List. The more powers you unlock, the more special moves you unlock.

Step 1 Play on easy mode and go for as many Collectibles, Feats & Missable Trophys! All of the Collectibles and Feats will Transfer to your next Playthrough, Valhallan Mode, which will only unlock once you have Completed one Playthrough.

Step 2 Do as many feats as you can on your 1st Playthrough. The feats that are like 30/30 or 100/100 etc. You might not be able to do them all in 1 Playthrough, but try and do more than half.

If He Be WorthyDefeat a giant enemy without taking any damage.

MISSABLE TROPHY
You must defeat a Giant enemy without taking ANY damage at all! I did this on Normal mode against the Frost Goliath on Asgard Besieged.
Here is an easy method I found useful myself... NOTE This method will unlock Ejected too.

Step 1. As soon as you start to fight the Frost Goliath dash forward towards him and use the Lightning power by holding down then grapple him as soon as you can with now you will be on his chest. Press three times (after each hit you will gain some health and Odinforce which you will need plenty of) then jump on to his arm, from there jump on his head and hit to perform a heavy attack.
Step 2. After you have pressed you will land back on the ground, use the Lightning attack by holding down again as soon as so the Frost Goliath doesn't recover! You should be able to grapple him now and will be on his chest, hit three times like before then jump on to one of his arms and hit for the heavy attack again.
Step 3. Now do exactly the same as step 2 but make sure you jump on to the other arm!
Step 4. Now do exactly the same as as step 2 but by now you should've destroyed all of th Frost Goliath's armour so stay on his chest and keep hiting after a few hits he will grab you and you will be on his chest and the icon will appear! Keep hitting and you will rip out the Jotun from his chest and If He Be Worthy will be yours.

SpelunkerOpen the Cave of Ages within 4 minutes.

Missable Trophy

To unlock this Trophy you have to open the Cave of Ages within 4 minutes, Here is a quick and easy way to do this.
When you try to open the Cave of Ages with Ymir will try to stop you and you'll start to fight. This is when the 4 minutes will start!

1 As soon as the fight starts he will start throwing Ice Balls at you, deflect them back at him and collect the blue runes to replenish your Odinforce magic. If it is full use your Lightning Storm on him as soon as you can. When you stop, block because he will attack you twice.

2 Now he will stop to rest and you should see a yellow point flashing, time to grapple him with

3 After you grab him you will be on his chest, now hit

Repeat 1, 2 & 3 until Ymir disappears and then go back to the Cave of Ages and try to open it again. Move out of the way as soon as you see Ymir's health return because he will start to attack again.

Reapeat all of this until you open the Cave of Ages. You should open the Cave of Ages after charging it with twice. If you don't see the tips/hints

Here is a little walkthrough for 14. Spiked(1) After you use the first Mjolnir's Leap, go inside the cave and turn right, continue going forward and the water on the floor should turn to ice. On the right, jump on the grapple point on the wall and pull yourself up and wait for the 1st set of spikes to pass!(2) Now, jump down and continue down the path, you'll see a small patch of thick ice on the floor, stand on it and wait for the 2nd set of spikes to pass. (3) Continue to go forward and destroy the Jade Turret, then jump on to the grapple point on the wall. Wait for the Spikes to clear from the wall before jumping on to the next grapple point (where the Jade Turret used to be.) You have to time your jump so you don't get hit Once you're on the last grapple point, jump up and you have completed this feat.

Barge HaulerComplete River Barge area with Mire Giant at 40% Health or better.

MISSABLE TROPHY

For this Trophy you need to complete River Barge area with the Mire Giant at 40% Health. You will be on the Barge for quite some time, but when you get off to destroy the mortars, that is when you will need to watch out for his health!

This can be complicated to do on your 1st playthrough, so I recommend going for it on your 2nd playthrough and use this method I found most useful... Step 1 Make your way up to the 1st mortar and immediately use Lightning Storm against the enemies, this should fill up your Power Surge meter. Hit to use your Power Surge and destroy the 1st mortar! Step 2 Make your way to the 2nd mortar and do the exact same as Step 1Step 3 Make your way to the 3rd mortar, grab the blue orb, it will give you infinite Odinforce magic for a very short time! Repeat Step 1Step 4 Perform the Mjolnir leap then repeat Step 1
Do it that way and the Trophy is yours!
